Method/Apparatus/Procedure:
The difference between the vapor pressures of the aqueous solution and the dry tetrachloromethane as a function of the ratio of vapor and liquid volumes was measured in an apparatus consisting of 3 tubes with mercury and a pressure adjusting device. The difference between the mercury levels in the middle tube and the reference tube gave the vapor pressure of the reference liquid. The solubility was calculated from the slope of 1/ΔP versus V
